4in Pre-Filter for R2C Pro Series

The 4in Pre-Filter for R2C Pro Series is an essential intake protection component designed for high-performance engine air filtration systems. This pre-filter wrap serves as the first line of defense against dust, debris, and contaminants before they reach your primary air filter element. Whether you're running modified turbocharged engines, off-road vehicles, or performance street applications, this OUTERWEARS accessory prevents premature filter clogging and extends overall system service intervals, directly protecting your engine investment.

Built with OUTERWEARS' proven pre-filter construction, this 4-inch component wraps around your R2C Pro Series filter to capture larger particulates before they load the main filter media. The design allows unrestricted airflow while maintaining structural integrity under high-velocity intake conditions common in forced-induction and naturally aspirated performance builds. Lightweight at just 0.08 lbs with compact dimensions of 4 x 2 x 5 inches, installation requires no modifications and fits cleanly within most intake tube configurations, making this a straightforward bolt-on maintenance upgrade.

Mechanics and performance enthusiasts benefit most from pre-filters in dusty environments—desert racing, construction-zone commuting, or high-mileage turbocharged daily drivers where air quality directly impacts engine longevity. The 4in pre-filter is specifically engineered for the R2C Pro Series platform, ensuring proper fitment and maximum filtration efficiency. Regular pre-filter replacement maintains optimized airflow and reduces the frequency of main filter service, delivering real cost savings over a vehicle's operational life while safeguarding turbo and engine components from abrasive contamination.
